SUSPENSION DEVICE FOB FLUID-COMPRESSORS.

To all whom it may concern:

Be it known that I, WALTER J. RICHARDS, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements in SuspensionDevices for Fluid-Compressors, of which the following is aspecification.

This invention relates to devices for suspending fluid compressors orother machines from the car body, and more particularly to a suspensiondevice adapted for supporting motor driven compressors such as employedto supply fluid under pressure for operating the brakes.

The compressor suspension heretofore commonly employed consists of acage like structure made of heavy strap iron surrounding the compressorand braced in different directions to give rigidity, particu larlyagainst jarring such as occurs at the time of starting and stopping thecar, the tendency to jar being increased by the nature of the cageconstruction which must take the thrust of the compressor at the lowerside thereof where it rests on the cage straps. The cage constructionalso renders the compressor diflicult of access and removal.

One object of my invention is to provide an improved compressorsuspension in which the suspending members are secured to and from amechanical unit with the compressor, so that rigidity is secured with asuspension construction of minimum weight.

Another object of my invention is to provide a compressor suspensionwhich permits of the ready removal of the compressor and also easyaccess thereto when in position.

In the accompanying drawing, Figure 1 is a side elevation, partly insection, of a compressor applied to a car body by means of my improvedcompressor suspension and Fig. 2 an end view thereof.

As shown in the drawing, the suspension device preferably comprisesthree straps,two of which are secured to the compressor at the gear endand the third strap at the commutator end. The straps 1-1 at the gearend are secured by bolts 2 to lugs 3 cast integral with the compressorbody and the lower ends a of the straps are turned inwardly at rightangles to the straps and the lugs 3 rest on the turned ends so asto-relieve.

right angles to the strap and the upper ends 10 of the straps 11 aresimilarly bent, so a that the three ends face in the same directlon.

A bracket 11 is secured by through bolts 12 to the car body 13 and isbent to form a centrally located recess 14: for the reception of the end9 of strap 5. A second bracket 15 is secured to the car body 13 by bolts16 and is provided with two recesses 17 for the ends 10 of the straps1-1. The hanger straps 11 and 5 being secured to the compressor 18 forma mechanical unit with the compressor and the upper supporting ends ofthe straps being turned in the same direction, the compressor may beinstalled in position by merely slipping the supporting ends into thecorresponding recesses in the brackets 11 and 15. When in position, thehangers are secured to the brackets by means of bolts 19.

It will now be evident that my improved compressor suspension providesrigidity with a minimum weight of material and that the compressor iseasy of access and may be readily removed by merely withdrawing thebolts which secure the supporting hangers to the brackets. By employingthree hanger straps the supporting ends are always substantially in thesame plane regardless of variations in the lengths of the straps, sothat registry with the recesses in the brackets is assured.

Having now described my invention, what I claim as new and desire tosecure by Let-v ters Patent, is

1. The combination with a compressor casing provided with front and rearintegral lugs, of vertical hanger straps rigidly secured to said lugsand provided with horizontally turned ends, and supporting strapsprovided with recesses for the turned ends of the hanger straps, tothereby rigidly suspend the compressor casing from the car body.

2. The combination with a compressor provided with integral lugs, ofhengerstraps' 1 In testiniony whereof I have hereunto set secured tosaid lugs and. having the lower my hand. ends bent to form supportingshelves for the lngsand the upper ends bent to face in the samedirection and brackets secured to the Witnesses: car body and providedwith recesses for re THos.
